How Installing Energy-Efficient Windows in Castle Pines Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
  • More efficient energy usage in your home: In Castle Pines where the summers can be quite hot, energy-efficient windows decrease the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save $443 a year on your bills.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Castle Pines

Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

Although the national average to install a single window is about $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, including number of windows, the location of your home, size, type, material and more.

It's also worth noting that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Castle Pines home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from several window installation companies to find the one that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Castle Pines

EcoWatch is different from most reviewers since we look at these companies through a sustainability lens. We have evaluated the top window installation companies in Castle Pines mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of parts, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Castle Pines' climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Castle Pines window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Castle Pines, CO Window Replacement FAQs

What is the average cost to install new windows?

The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the different types of windows?

There are several different kinds of windows you can get for your house, such as picture windows, slider windows, double-hung and single-hung windows, awning windows, casement windows, transom windows and bay windows.

Do you really need to use a window installation company?

You should use a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.

How often should you replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
